Hello again Abigail

Yes you understood my question, I escaped the grammarbot but i do think it was perhaps missing a comma somewhere :)

It is very important to keep in mind that old age does NOT necessarily come with dementia. Even individuals who carry the ApoE4 variant won't necessarily develop the disease, provided their environmental factors as well as mental and physical health can balance things out.

Ok, now I'm clear. Lifestyle is a factor (I wonder to what extent? % wise) if you have the variant.

I have been out for a cycle today and so that's perked me up and warmed me up, a healthy meal this evening and I shall have ticked most of the boxes again :)

Thanks for taking the time to respond, and enjoy the rest of your weekend.

Asher
